Sodium carboxymethyl selulose (CMC) ni anionic, urunigi rugororotse, amazi ya elegitoronike ya elegitoronike, ikomoka kuri selile naturel na aside ya chloroacetike ihindura imiti.Igisubizo cyacyo cyamazi gifite imirimo yo kubyimba, gukora firime, guhuza, gufata amazi, kurinda colloidal, emulisation no guhagarikwa, kandi irashobora gukoreshwa nka flocculant, chelating agent, emulsifier, umubyimba, ibikoresho bigumana amazi, agent ingana, ibikoresho bya firime, nibindi. ., ikoreshwa cyane mubiribwa, ubuvuzi, ibikoresho bya elegitoroniki, imiti yica udukoko, uruhu, plastike, icapiro, ububumbyi, inganda zikora imiti ya buri munsi nizindi nzego.

Sodium carboxymethyl selulose muri rusange ni ifu ikomeye, rimwe na rimwe granular cyangwa fibrous, umweru cyangwa umuhondo wijimye wijimye, nta mpumuro idasanzwe, ni imiti ya macromolecular, ifite ubushuhe bukomeye, irashobora gushonga mumazi, mumazi kugirango ikore igisubizo kiboneye gifite hejuru gukorera mu mucyo.Kudashonga muri rusange ibisubizo kama, nka Ethanol, ether, chloroform na benzene, ariko birashobora gushonga mumazi, bigashonga mumazi biratinda cyane, ariko ibishishwa biracyari binini cyane, kandi igisubizo cyamazi gifite ubwiza runaka.Ibikomeye mubidukikije muri rusange birahagaze neza, kuko bifite amazi runaka hamwe nubushuhe, ahantu humye, birashobora kubikwa igihe kirekire.

Process Uburyo bwo kubyaza umusaruro

1. Uburyo bwo gukoresha amazi

Amazi yamakara ni inzira yo kubyara hakiri kare mugutegura inganda za sodium carboxymethyl selulose.Muri ubu buryo, selile ya alkali selile na etherifyinga ikora mugisubizo cyamazi kirimo ion ya ogisijeni yubusa, kandi amazi akoreshwa nkigikoresho cyo kubyitwaramo mugihe cyo kubyitwaramo, nta muti wa organic.

2. Uburyo bwo gukemura ibibazo

Uburyo bwa solvent nuburyo bwa solvent organique, nuburyo bwo kubyaza umusaruro bwakozwe hashingiwe kuburyo bwamazi yo hagati yo gusimbuza amazi nimbuto kama nkibisubizo.Inzira ya alkalisation na etherifike ya alkali selile na acide monochloroacetic mumashanyarazi.Ukurikije ingano yuburyo bwa reaction, irashobora kugabanywa muburyo bwo gukata hamwe nuburyo bwo koga.Ingano yumuti ukoreshwa muburyo bwa pulping ni nini cyane kuruta uburyo bwo guteka, kandi ingano yumuti ukoreshwa muburyo bwo gukata ni igipimo cyuburemere bwubunini bwa selile, mugihe ingano yumuti ukoreshwa muburyo bwa pulping ni igipimo cyuburemere bwubunini bwa selile.Iyo sodium carboxymethyl selulose yateguwe nuburyo bwo koga bwo koga, reaction ikomeye iba iri muburyo bworoshye cyangwa ihagarikwa muri sisitemu, ubwo rero uburyo bwo koga bwitwa nanone uburyo bwo guhagarika.

3. Uburyo bwihuse

Uburyo bwa Slurry nubuhanga bugezweho bwo gukora sodium carboxymethyl selulose.Uburyo bwa slurry ntibushobora kubyara gusa sodium karboxymethyl selulose, ahubwo inatanga sodium carboxymethyl selulose ifite impamyabumenyi isimbuye kandi isimbuzwa kimwe.Uburyo bwo kubyaza umusaruro uburyo bworoshye burakurikira: ifu yipamba yashizwemo ifu yoherejwe mumashini ihagaritse alkalizing ifite inzoga ya isopropyl, hamwe na sodium hydroxide yumuti wongeyeho mugihe cyo kuvanga iba alkalize, kandi ubushyuhe bwa alkalizing ni 20 ℃.Nyuma ya alkalisation, ibikoresho byapompa mumashini ihagaritse ya etherifying, hanyuma hongerwaho igisubizo cya alcool ya isopropyl ya acide chloroacetic, kandi ubushyuhe bwa etherifing ni 65 ℃.Ukurikije ibicuruzwa byihariye bikoreshwa nibisabwa byujuje ubuziranenge, kwibanda kuri alkalisation, igihe cya alkalisation, ingano ya agent ya etherifying hamwe nigihe cya etherification nibindi bikoresho bishobora guhinduka.

Scope Urwego rusaba

1. CMC ntabwo ari emulisifike nziza gusa kandi ikabyibuha mugukoresha ibiryo, ariko kandi ifite ubukonje buhebuje no gushonga, kandi irashobora kunoza uburyohe bwibicuruzwa no kongera igihe cyo kubika.

2. Muri detergent, CMC irashobora gukoreshwa nkigikoresho cyo kurwanya ruswa, cyane cyane kuri hydrophobique synthique fibre fibre anti-fouling reaction, cyiza cyane kuruta fibre ya carboxymethyl.

3. Mu gucukura peteroli birashobora gukoreshwa mukurinda amavuta Iriba nka stabilisateur ibyondo, kubika amazi, ingano ya buri riba ryamavuta ni 2 ~ 3t Iriba rito, Iriba ryimbitse 5 ~ 6t.

4. Ikoreshwa mu nganda yimyenda nkibikoresho bingana, gucapa no gusiga irangi ryijimye, gucapa imyenda no kurangiza.

5. Ikoreshwa nkigikoresho cyo kurwanya anti-gutuza, emulifier, ikwirakwiza, umukozi uringaniza, ifata, irashobora gutuma igice gikomeye cy irangi kigabanywa neza mumashanyarazi, kugirango irangi ridashyirwa mugihe kirekire, ariko kandi rikoreshwa muburyo bworoshye .

6. Nka flocculant mugukuraho ioni ya calcium kuruta sodium gluconate ikora neza, nkuguhana cation, ubushobozi bwo guhana kugeza kuri 1.6ml / g.

7. Mu nganda zimpapuro zikoreshwa nkibikoresho bipima impapuro, birashobora kuzamura cyane imbaraga zumye nimbaraga zitose zimpapuro zamavuta, kwinjiza wino no kurwanya amazi.

8. Nka hydrosol mu mavuta yo kwisiga, ikoreshwa nkibintu byiyongera mu menyo yinyo, dosiye yayo igera kuri 5%.
